Enjoy, do let me know earlier if you want coz need queue
Old car normally have bad grounding. tried on 15 yrs wira which vibrate like hell, after installed the VS it reduce the vibration by around 30%, and if i install grounding on it, then no much vibrate anymore (90% improvement). If i take off the VS with grounding cable still on it vibrates again. So VS + grounding is very important for bad grounded car.

Note that Saga BLM is one of an example of bad grounding new car. Myvi however have pretty good stock grounding.

Sorry bro i only selling VS here. For grounding it's all depending on how much performance that you want to achieve, if you want to get a slight performance then can try HKS ori set. If you want something real in performance, at least get 10mm thick power cable. I was thinking to get some real good grounding cable in, but wait for my new 

Hi bro, price will be disclosed next week probably, but promised what i chose is very good quality and same concept of my VS, my grounding cable will beat most branded one in market.

Bro adding grounding cable would help even more heheh.
